i To all fof/om it mag/concern.'

Be it known that I, XVILLIAM L. FOSTER, a citizen of the United States, residing at Dayton, Yin the county of Montgomery and State of Ohio, have invented certain new and useful Improvements in Friction- Hinges, of which the following is a specilication, reference being had therein to Athe accompanying drawing.

This 'invention relates to friction hinges for windows, -doors and the like,'and more particularly to a lcombined hinge and 'casement adjuster. f

The objecto -the invention is to provide a means of holding easement sash in any desired position which will be very simple and inexpensive in its construction and will firmly hold the easement in adjusted positions. v

A further object is to provide such a casement adjuster which will be practically concealed, the only visible portions' being the face plates and operating-handle.

- In the accompanying drawings, Figure 1 is a front elevation of a window Acasing and window showing my invention applied thereto; Fig. 2 is a fragmentary view of the window and window frame with a portion of the latter' broken away to show the invention embodied therein; and Fig. 3 isa detail view of the showing the parts separated.

In these drawings I have illustrated .one embodiment of my invention 21nd v have shown the same as applied to the lower corner of an inwardly swinging sash. As here shown the device constitutes one of the supporting hinges for the Asash and the fixed part of the device is mounted in the window frame beneath the sash,'but it will be understood that the location of the de vice is a matter of convenience. only and that with but slight modification it can be applied in various positions, for example, when used in connection with a window having'a very low sill it will be preferable to arrange the device at a point between the upper and lower hinges where-it will be readily accessible for operation. v

As here shown the device consists oftwo hinge members, one of which comprises a face plate adapted to be secured to the sash 2, by means of screws or otherwise, and

vprovided with a hinge pin or post 3. ln the arrangement here shown this pin, which is arranged parallel with the vertlcal edge of easement adjusting hinge.

below the llower edge of thev the inner sill 4 .of the The second hinge memi the sash, extends sash and through wmdow frame 5.

ber comprises' a 4face plate 6 having `ar thereof a part 7 having a socket adapted to receive` the hinge pin 3, this socket being of such a character that it can be clamped about the hinge pin to grip the same and resist its movement.: Ashere shown this part is in the form of a split sleeve. Mounted on the face plate 6 is an actuating device 8 which vextends rearwardly from the face plate and is yoperaranged in the rear tively connected with the split sleeve. Pref 2 device is in the form" a shoulder bearing erably, this actuating of a bolt 8 having against the face plate and having its rear end screw-threaded into a. lug 9 on the outer portion of the split sleeve, the inner portion being held against movement. The 'outer end of the bolt is provided with a knob or handle l0 by means of which the bolt may be rotated. In the present instance the socket is shown as formed integral with' theface'plate and when the face plate is secured to the window'frame Athe latter is provided with a recess 1l to receivejthe clampingy member 7.

he operation of the device will beraadily understood from the foregoing description and it will be apparent that have provided an adjusting hinge for a sash or other hinged member lwhich will take the place of one of the usual hinges and which is of such a character that the operating parts, except the knob, are entirely concealed and which can be applied to the sash and frame with but very little cutting, it being onlynecec- 95. ing memberand an opening to permit the I sary to form the recess to receive the clamppassage of the hinge pin. Furthenit will be apparent that the device is very easy of operation andcan be actuated to firmly secure the sash in any adjusted position, and moreover', that the device is of such 'a character it isynot liable to be injured should force be applied to the sash without releasing the clamping device. lt will further be apparent that While I have shownthe device as applied to the lower corner of an inwardly swinging sash it can, ywith obvious Vao modifications, be adapted to outwardly swinging sash and to diderent ieee-tions on the sash.

While I have shown and described one embodiment of'my invention it will be unmember.

derstood that this has been chosen forthe cess in said `frame and having` a part ar-e ranged to receive said hinge pin, said part having -a clamping action to grip said pin, Iand an actuating device mounted on the face of said frame and' operatively con'iectedf with the clamping part of said second hinge i 1* 2'. The combination, with a window or f door frame and a sash mounted therein, said frame having a recess beneath said sash and v1n ahnement with one oi the vertical edgestheleof, of a hinge memberl comprisingr a face plate mounted onlsaid frame in front ol? said rece'ss, and a clailnping device mounted in said recess, an actuating device mounted on said face plate and connected with said clamping device, and a second hinge member con'iprising a plate secured to said sash and havilw a iinevtendinir downwardly l'roin C n vsaid sash and rotatably mounted ii` said clamping?,r device. y

3. A. easement iadjustiiaev hinge romprisiner a. hinge member havingri` a hinge pin, a seeond hinge member eoinprisiingr a clamping device havingl a soi-liet to receive said hinge `pin, an attachingv plate to support said clamping device \vith its socket in alineineiit with said hinge pin, and an actuating' device e.\tendini? f` througl'i said attachingplate and operatively connected with said elampinIiY device.
